General procedure to find out the problem?
I really like this page, it is great to find so many tips on how to save money by repairing your mac by yourself.
Unfortunately, I was not able to find a procedure to find out what causes the problem and therefore what needs to be replaced.
I can't switch on my macbook (white, from 2006). The battery is working, RAM and HD are OK. Ithink that either the keyboard is broken or the logic board. Is there a method to find out which one causes the problem before buying expensive parts to repair it?
